Preface xi 1 INTRODUCTION TO TEXTBRIDGE Welcome to ScanSoft's TextBridge TM Pro 9.0, optical character recognition (OCR) software for Microsoft WindowsTM 95, 98, 2000 and Windows NT 4.0. This chapter provides an introduction to TextBridge including: x x x x x x Basic OCR concepts Features and benefits Characteristics of documents TextBridge can recognize Input image file formats Output text file formats Output image file formats BASIC OCR CONCEPTS OCR technology enables you to convert paper documents into fully editable text on your computer. Originally, OCR technology performed simple character recognition of text characters, numbers, and symbols. Today, TextBridge OCR includes full document recognition including recognizing text plus formatting such as headlines, multiple columns, tables, and running headers and footers and capturing photographs and line drawings. TextBridge even retains the layout of the original document when possible. TextBridge Pro User's Guide 1­1 You can use TextBridge to scan and convert printed pages to text documents for your word processor, spreadsheet program, web browser, database program, or other text application. Pages may be from most sources, including computer printers, fax machines, photocopiers, magazines, and newspapers. Pages can be black and white or color. TextBridge can also recognize standard page image files from fax modems, image applications, and other sources. Using the latest document recognition technology from ScanSoft, TextBridge OCR uses its recomposition capability to produce a fully-editable electronic document with the original pictures and document layout (Figure 1­1,). Original document Recomposed document in word processor Figure 1­1. TextBridge document recomposition 1­2 TextBridge Pro User's Guide In most cases, TextBridge understands your original document's format and maintains the layout, including columns, headers, footers, pictures, and picture captions. Pictures can be black and white, grayscale, or color. Recomposition is possible only if your text program supports pictures and layout. For example, recomposition is supported in Microsoft Word and Corel WordPerfect but not in Notepad. Forms and documents created in desktop publishing programs are usually too complex for recomposition by TextBridge as well as your word processor. As a result, the text and pictures are retained but the full layout is not. FEATURES AND BENEFITS TextBridge offers many features designed to increase your productivity. Whether you need to capture a simple one-page letter, a magazine article, a spreadsheet, or a long transcript, TextBridge can save you valuable time and effort. In addition, TextBridge provides all the capabilities that experienced OCR users expect. With TextBridge, you can import most paper documents or document image files to your computer. TextBridge attains the highest degree of OCR accuracy and provides the output in fully editable form in your favorite text program. Introduction to TextBridge 1­3 New Features TextBridge offers these major new features to increase your productivity: x Improved OCR accuracy. Dramatically save time and eliminate retyping. Color and grayscale pictures and text. Recognition and output of color and grayscale pictures. Recognition of color text and text on a color or shaded background and output of black on white or white on black. Improved table recomposition. Advanced analytical capability results in improved table reformatting. Ability to edit the entire table as well as individual cells for improved recognition. Cell table recomposition is supported even if you do not choose to retain layout. Flexible multi-page document handling. Ability to view and manipulate the pages of a document using the page thumbnails. Zone multiple pages before recognition. Process the pages of a document in any order. Delete, rearrange, and re-recognize individual pages. You can also control the output. Additional language recognition. Ability to recognize many Eastern, Central, and Western European languages. Multiple language recognition. Ability to recognize multiple languages on the same page if all languages belong to the same language group. Improved usability and user assistance. Enhanced ease of use including a redesigned user interface and extensive user assistance. User assistance includes a multimedia assistant, information screens, context-sensitive tips, status area messages, Help system, and printed and online documentation. x x x x x x 1­4 TextBridge Pro User's Guide x TextBridge Assistant. An easy-to-use assistant, guides you through each step of the most common TextBridge activities, such as how to scan a page and send it to Word, recognize an image file, and recognize just part of a page. Improved batch processing. The ability to select multiple files and process each file separately plus the ability to schedule processing for a specific time in the future. Integration with e-mail programs. Input to popular programs such as Lotus cc:Mail, Microsoft Outlook, and America Online (AOL). Integration with the latest scanners. TextBridge works with the most recent scanners. The ScanSoft Web site at www.scansoft.com provides the latest information about supported scanners and getting your scanner to work with TextBridge. HTML 4.0 output and WYSIWYG capability. Output files in the latest version of HTML and preserve the original look using cascading style sheets. Dual page scanning. Scan both pages of an open book at the same time but handle them as two separate pages. Easy database importing. Use of standard delimited text file output that allows you to import data into many databases. x x x x x x Introduction to TextBridge 1­5 Enhanced Features In addition to the new features, TextBridge offers enhanced features that were available in previous versions. These features are described in the following list: x Instant AccessTM. Start TextBridge within most Windows text programs such as Word or Excel. After recognizing and converting the page, TextBridge then automatically pastes recognition data (text and pictures) directly into the program's open document. ToolTips. Instant context-sensitive information about commands, dialog boxes, and buttons on the interface. Document recomposition. TextBridge offers true document recomposition to retain your original page layout. It reproduces multiple columns, tables, and pictures and keeps them in the same location as they are in your original document. For example, when you specify output to the Microsoft Word TM or Corel WordPerfect ® format, TextBridge can retain the original document layout in fully-editable form, even for pages containing tables, line art, reverse video, drop caps, insets, and pictures. When you edit the document, the original text flow is maintained. When you specify output to the Microsoft Excel TM or Lotus 1-2-3 format, spreadsheets and cell tables retain their original layout as cell tables, not tabbed columns. When you edit the table information, the lines move to fit. TextBridge supports formats for the programs that retain page layout in the following list: Internet Explorer Netscape Word 6.0, 7.0, 97, and 2000 Word Perfect 6.0, 6.1, 7.0, 8.0, and 9.0 Any word processor that supports RTF x x 1­6 TextBridge Pro User's Guide Retaining pictures is independent of retaining layout. Some text programs retain pictures even though they do not retain layout. x Page Types. TextBridge provides many predesigned Page Types to make processing more efficient. You do not have to go through a complicated process of determining and specifying settings for common types of pages. These Page Types automatically provide appropriate settings for the type of page you want to process. For example, there is a Letter page type and a Magazine page type that automatically activate settings for improved results for letters and pages from magazines. Automatic zoning. TextBridge automatically zones your page into text, picture, and table zones. Zone editing. You can edit the automatically recognized zones to further refine the zoning. Use zone editing to increase the accuracy and efficiency of page processing by reshaping zones, specifying the language, and renumbering them. Built-in ProofreaderTM. After document recognition, you can use the built-in proofreader to view and accept or correct any words that TextBridge suspects may not be recognized accurately. The proofreader provides suggestions from which you may choose. Dynamic OCR training. You can train OCR to improve recognition accuracy as the job progresses. Use dynamic training with difficult documents, such as faxes or multi-generation photocopies. TextBridge enables you to interact with the OCR process by viewing then accepting or correcting its automatic recognition decisions. The software actually learns special symbols and words. Output files to the latest version of programs. These include Microsoft Word 2000 and Excel 97, WordPerfect 9.0, and Adobe FrameMaker 5.0. x x x x x Introduction to TextBridge 1­7 Other Features In addition to the features listed in the previous sections TextBridge provides these other features. x x Windows 98 and 2000 compatibility. Broad scanner support. TextBridge supports most popular desktop scanners with TWAIN device interface standard. Image processing. TextBridge accepts a wide range of images from a variety of sources for processing. Specifically, the program imports and recognizes online document images in BMP, PCX, DCX, TIFF, and XIF formats that originate from fax modems and other sources. For more information, see the "Input Image File Formats" section in this chapter. Deferred processing. TextBridge enables you to scan all the pages of a document to a TIFF or XIF file, then later open the image file for document recognition. You can also save all the pages to a multi-page image file or save each page as a separate file. Output text file formats including HTML. TextBridge supports a number of output text file formats, including word processor, desktop publishing, spreadsheet, HTML, and database formats. Now you can process your text for publication on the Web. x x x 1­8 TextBridge Pro User's Guide x Preview of page images. TextBridge provides a set of tools for previewing page images before processing them. You can manually define areas of page images as zones to be processed and capture only the text, tables, or pictures you want. You can also edit the automatic zoning by adjusting the text, table, and picture zones. Zone templates. After you create a set of zones, TextBridge lets you save and reload zone templates for new jobs. In this way you can consistently process or ignore specific areas on the same type of pages and save time without rezoning each page. Re-usable training data. After you interactively train OCR, you can save the training data in a file. You can reload this training file for similar documents of the same page type. Using this training file assures the highest recognition accuracy without your having to repeat the training. Custom dictionaries. To improve recognition accuracy further, you can create specialized word lists (scientific terminology, proper names, acronyms, and so on) within TextBridge or in ASCII text files and load them into TextBridge. Two-sided document processing. If your scanner has a sheet feeder, you can scan the fronts (odd sides) of the pages first, then flip the stack and scan the reverse (even) sides. When scanning and recognition are complete, TextBridge automatically collates the text and keeps it in the original order. x x x x Introduction to TextBridge 1­9
